This is an informative video about the largest creatures to ever live on earth, by type (ie. largest arthropod, largest land mammal — both seen above, largest flying creature, etc.). Did you know the largest arthropod was an 2.5 meter (8.5-foot) millipede-looking beast that was as wide as you are and weighed over 1,000-pounds?
Amazingly, the largest creature on earth to ever exist is still around — the blue whale! That’s pretty cool, huh?
